Risk prediction of complicated course in patients undergoing major head and neck surgery with free flap reconstruction.

The British Association of Oral and Maxillofacial Surgeons (BAOMS) Quality and Outcomes in Oral and Maxillofacial Surgery (QOMS) reconstructive audit aims to provide surgical teams with risk adjusted comparative performance data. The goal is to enable surgeons to optimise surgical pathways. Risk adjustment requires that data on appropriate predictive variables are collected.

Applying the British Association of Oral and Maxillofacial Surgeons quality outcomes metrics to a regional Australian oncology and reconstructive service: benchmarking the data to audit clinical outcomes in emerging, regional, and small-volume centres.

The traditional model of centralisation of care, whilst having many advantages, also requires adaptation and upscaling to meet the requirements of both regional areas and the increasing urban sprawl. However, to ensure comparable outcomes with current major centres, this transition, when required, must be delivered in a safe and effective manner. Our project, which utilised the British Association of Oral and Maxillofacial Surgeons (BAOMS) recently published outcome data from the Quality and Outcomes in Oral and Maxillofacial Surgery (QOMS) project to benchmark data prospectively collected from a small-volume, emerging centre in Northern Queensland, was the first of its kind in terms of validation studies.

Optimised fast-track protocols in total knee arthroplasty determine shorter hospitalisation time and lower perioperative/postoperative complications.

Purpose: This literature review aims to present evidence-based clinical recommendations for the eight most debated topics related to perioperative management in total knee arthroplasty: counselling, prehabilitation, transfusion risk, tranexamic acid, drainage, analgesia, urinary catheter and compression stockings.

Methods: A multidisciplinary team conducted a systematic review on these topics. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for the literature review and result presentation.

Allografts use in orthopedic surgery: trend change over the past 11 years from a regional tissue bank.

Allografts are the second most transplanted tissue in medicine after blood and are now increasingly used for both primary and revision surgery. Allografts have the advantages of lower donor site morbidity, availability of multiple grafts, and shorter operative time. The Banks represents the bridge between Donor and Recipient and guarantees the quality and safety of the distributed allografts Given the increasing interest in these tissues, a retrospective analysis of data collected from the Regional Musculoskeletal Tissue Bank registry over an 11-year period (2009-2019) was conducted.

Medium-long-term follow-up of slipped capital femoral epiphysis treated with in situ fixation and patient-acceptable symptom state evaluation.

This study evaluates the Patient Acceptable Symptom State (PASS) in patients with slipped capital femoral epiphysis (SCFE) treated with in situ fixation, focusing on medium to long-term outcomes and quality of life. Its primary goal is to establish a subjective well-being cutoff, using subjective methods and the iHOT33 scale, for assessing patients in future studies. Additionally, it explores functionality differences between mild and moderate-severe SCFE, case series epidemiology and potential complications.

Implementation of Robotic Exoscope in Minimally Invasive Corpectomy at Thoracolumbar Junction for the Treatment of Traumatic Spinal Cord Compression.

The development and diffusion of minimally invasive (MI) approaches have coincided with improvements in magnification systems. The exoscope will probably open a new era in new technologies in spinal surgery. This study reports a retrospective series of 19 thoracolumbar (T11-L2) burst fractures with anterior column failure and cord compression, treated with MI corpectomy and spinal decompression assisted by a three-dimensional high-definition exoscope (Video 1).

Transforaminal lumbar interbody fusion with a tantalum cage: lumbar lordosis redistribution and sacral slope restoration with a modified posterior technique.

Background: Transforaminal lumbar interbody fusion (TLIF), a commonly used procedure in spine surgery, has the advantage of a lower incidence of nerve lesions compared to the posterior lumbar interbody fusion (PLIF) technique. The intersomatic arthrodesis has always been carried out with a single tantalum cage normally used for PLIF. Tantalum is a metal that is particularly used in orthopedic surgery.

Integrated spine trauma team protocol: Combined neurosurgical and orthopedic experience for the management of traumatic spinal injuries.

Objectives: During the last decades, spine surgery has grown exponentially. In spite of that, it remains a surgical specialty without a well-defined own certification. It is usually carried out, separately, by neurosurgeons and orthopedic surgeons, even if there is an overlapping of competence and skills.

Comparison of oral and maxillofacial trauma during the first and third lockdown of the COVID-19 pandemic in the United Kingdom.

The incidence and management of maxillofacial trauma was compared between the first and third lockdowns in the United Kingdom due to the COVID-19 pandemic. From 6 January, 2021 to 8 March 2021, the units that had participated in the collection of data during the first lockdown were asked to update their information into the same database for the third. Nine units participated with 929 entries.

Combining wavelength importance ranking to the random forest classifier to analyze multiclass spectral data.

Near Infrared (NIR) is a type of vibrational spectroscopy widely used in different areas to characterize substances. NIR datasets are comprised of absorbance measures on a range of wavelengths (λ). Typically noisy and correlated, the use of such datasets tend to compromise the performance of several statistical techniques; one way to overcome that is to select portions of the spectra in which wavelengths are more informative.

Identifying the most relevant tablet regions in the image detection of counterfeit medicines.

This paper proposes a novel image-based approach to detect counterfeit medicines and identify the most relevant regions of the tablet in the task of classification. Images of medicine tablets undergo an initial pre-processing step which (i) removes the background to find the region of interest, (ii) clusters individual pixels into super-pixels, and (iii) extracts features containing color and texture information. The classification relying on Support Vector Machine (SVM) defines the class the respective image will be inserted into.

Management of oral and maxillofacial trauma during the first wave of the COVID-19 pandemic in the United Kingdom.

We assess the effect of coronavirus disease 2019 (COVID-19) on UK oral and maxillofacial (OMF) trauma services and patient treatment during the first wave of the pandemic. From 1 April 2020 until 31 July 2020, OMF surgery units in the UK were invited to prospectively record all patients presenting with OMF trauma. Information included clinical presentation, mechanism of injury, how it was managed, and whether or not treatment included surgery.

Applying the British Association of Oral and Maxillofacial Surgeons quality outcomes metrics to a UK oncology and reconstructive surgery service - benchmarking the data.

The British Association of Oral and Maxillofacial Surgery is soon to implement the Quality Outcomes in Oral in Maxillofacial Surgery (QOMS) to provide a platform for quality management across the specialty in the UK. The initial oncology and reconstruction audits for QOMS involves data collection on specific procedures and metrics. The aim of this report is to determine their appropriateness using extant audit datasets in our institution that overlap substantially with the QOMS audits.

BAOMS QOMS: findings from the pilot phase and lessons learned in the feasibility evaluation of a national quality improvement initiative.

The BAOMS QOMS pilot was developed and run in six England OMFS units between December 2019 - April 2020. The aims of this pilot project were: to evaluate feasibility of the questionnaires developed for the audit and how effective they were with regards to quality improvement, to test the processes associated with the data collection system and finally, to provide baseline data to support patient data collection without the requirement of prospective consent. The pilot included a series of six audits (oral and dentoalveolar [ODA], oncology, orthognathic, reconstruction, trauma, and skin).

Management of odontogenic cervicofacial infections presenting to oral and maxillofacial units during the first wave of the COVID-19 pandemic in the United Kingdom.

On 25 March 2020, the Chief Dental Officer issued national guidance restricting the provision of all routine, non-urgent dental services in response to the spread of COVID-19. We analysed odontogenic cervicofacial infections (CFI) presenting to oral and maxillofacial surgery (OMFS) departments during the first wave of COVID-19 in the United Kingdom. From 1 April 2020 until 31 July 2020 a database was used to prospectively collect records for all patients with CFI who presented to oral and maxillofacial teams.

Hyaluronic acid fillers in lip augmentation procedure: a clinical and histological study.

Several approaches have been proposed for soft tissue augmentation using injectable materials for lip and soft-tissue augmentation due to their physical and biological properties. Hyaluronic acid represents a natural component of the connective tissues, related to wound healing and skin regeneration. The aim of this research was to investigate the clinical and histological effectiveness of cross-linked hyaluronic acid for lip augmentation.

Results of flap reconstruction: categorisation to reflect outcomes and process in the management of head and neck defects.

The reporting of the outcomes of flap reconstruction is often based on numerical success rates. Whilst this remains a useful variable with which to measure success, it is limited in its ability to reflect the complex processes involved. The lack of consistency in the categorisation of outcomes of flap reconstruction in the head and neck could potentially lead us to lose the opportunity to fully capture the implications of its success or failure, or both.

Revision Anterior Cruciate Ligament Reconstruction With Hamstrings and Extra-articular Tenodesis: A Mid- to Long-Term Clinical and Radiological Study.

Purpose: To present the mid- to long-term clinical and radiographic outcomes of a series of patients who underwent revision anterior cruciate ligament (ACL) reconstruction with doubled gracilis and semitendinosus (DGST) autograft and a lateral extra-articular tenodesis (LET).

Methods: Patients who underwent revision ACL reconstruction with DGST and LET by a single surgeon between January 1997 and December 2013 were included. Revision was indicated by ACL failure noted on magnetic resonance imaging, persistent clinical instability, or laxity on clinical exam.

The satisfactory growth and development at 2 years of age of the INTERGROWTH-21 Fetal Growth Standards cohort support its appropriateness for constructing international standards.

Background: The World Health Organization recommends that human growth should be monitored with the use of international standards. However, in obstetric practice, we continue to monitor fetal growth using numerous local charts or equations that are based on different populations for each body structure. Consistent with World Health Organization recommendations, the INTERGROWTH-21 Project has produced the first set of international standards to date pregnancies; to monitor fetal growth, estimated fetal weight, Doppler measures, and brain structures; to measure uterine growth, maternal nutrition, newborn infant size, and body composition; and to assess the postnatal growth of preterm babies.

Body composition at birth and its relationship with neonatal anthropometric ratios: the newborn body composition study of the INTERGROWTH-21 project.

BackgroundWe aimed to describe newborn body composition and identify which anthropometric ratio (weight/length; BMI; or ponderal index, PI) best predicts fat mass (FM) and fat-free mass (FFM).MethodsAir-displacement plethysmography (PEA POD) was used to estimate FM, FFM, and body fat percentage (BF%). Associations between FFM, FM, and BF% and weight/length, BMI, and PI were evaluated in 1,019 newborns using multivariate regression analysis.

Precision of recumbent crown-heel length when using an infantometer.

Background: Crown-heel length (CHL) measurement is influenced by technique, training, experience and subject cooperation. We investigated whether extending one or both of an infant's legs affects the precision of CHL taken using an infantometer. The influence of staff training and infant cooperation were also examined.

Systematic Review of the Methodological Quality of Studies Aimed at Creating Gestational Weight Gain Charts.

A range of adverse outcomes is associated with insufficient and excessive maternal weight gain in pregnancy, but there is no consensus regarding what constitutes optimal gestational weight gain (GWG). Differences in the methodological quality of GWG studies may explain the varying chart recommendations. The goal of this systematic review was to evaluate the methodological quality of studies that aimed to create GWG charts by scoring them against a set of predefined, independently agreed-upon criteria.
